Groat oil content and composition are important quality traits in oats (Avena sativa L). These traits are controlled by many genes with additive effects. The chromosomal regions containing these genes, known as quantitative trait loci (QTL), can be discovered through their close association with markers. This study investigated total oil content and fatty acid components in an oat breeding population derived from a cross between high oil ('Dal') and low oil ('Exeter') parents. A genetic map consisting of 475 DArT (Diversity Array Technology) markers spanning 1271.8 cM across 40 linkage groups was constructed. QTL analysis for groat oil content and composition was conducted using grain samples grown at Aberdeen, ID in 1997. QTL analysis for multiple agronomic traits was also conducted using data collected from hill plots and field plots in Ottawa, ON in 2010. QTLs for oil content, palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2) and linolenic acid (18:3) were identified. Two of the QTLs associated with oil content were also associated with all of the fatty acids examined in this study, and most oil-related QTL showed similar patterns of effect on the fatty acid profile. These results suggest the presence of pleiotropic effects on oil-related traits through influences at specific nodes of the oil synthesis pathway. In addition, 12 QTL-associated markers (likely representing nine unique regions) were associated with plant height, heading date, lodging, and protein content. The results of this study will provide information for molecular breeding as well as insight into the genetic mechanisms controlling oil biosynthesis in oat.

An analysis of interrater agreement across multiple respondents on anecdotal assessments and correspondence between functional analysis outcomes was completed. Experiment I evaluated overall agreement among multiple respondents (direct-care staff) on the hypothesized function of each residents (28 adults with mental retardation) problematic behavior using the Motivational Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST). Results of the questionnaires indicated that respondents agreed on the function of the problematic behavior for 10 of the 28 residents. Experiment II examined whether, for selected cases in which 4 out of 5 respondents agreed on the function of the problematic behavior, correspondence occurred between functional analyses and anecdotal assessments outcomes. Two of the 6 functional analyses did not evoke the problematic behavior. However, 4 functional analyses did produce corresponding outcomes suggesting that, when the functional analyses produced interpretable data, the results of the functional analyses corresponded with those of the anecdotal assessments.

We administered the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF) to five raters and compared the results with functional analysis outcomes for 12 cases in which agreement was obtained for at least four out of five raters on either anecdotal assessment. The scores for functional categories on the MAS and QABF were ranked by averaging the scores for the raters who agreed on the primary maintaining variable. Functional analysis results were ranked by examining average responding across all conditions. A comparison showed correspondence between the highest category and the highest functional analysis condition for 10 out of 11 cases for the MAS and all 10 cases for the QABF. Correspondence for the category and condition ranked second was found for 2 out of 11 cases for the MAS and 2 out of 10 cases for the QABF. The magnitude of difference between categories on the MAS/QABF did not appear to predict the amount of difference in responding in the corresponding functional analyses.

[ES] La cirugía laparoscopia está considerada uno de los principales avances quirúrgicos en las últimas décadas. Esta técnica ha demostrado numerosas ventajas comparadas con la cirugía convencional abierta y ha sido extensamente usada para procesos quirúrgicos en el área abdominal. Para el paciente, la cirugía laparoscópica supone diversas ventajas, como por ejemplo menor dolor post operativo, tiempos de recuperación menores, menor riesgo de infección, o reducción del trauma. Para el cirujano en cambio, la situación es completamente diferente, esta práctica requiere mayor esfuerzo, concentración y estrés mental que la práctica convencional abierta. Además fuerza al cirujano a adoptar posiciones no-neutras en falanges, manos, muñecas, y brazos. Estas posturas no-neutras son la principal causa de fatiga muscular y aumentan el riesgo de problemas musculo-esqueléticos. Estos problemas han sido ampliamente estudiados por diferentes equipos de investigación, los cuales están tratando de mejorar la experiencia del cirujano en el quirófano. El enfoque utilizado en este estudio es diferente del utilizado anteriormente por la mayoría de estos equipos, los cuales suelen propones soluciones basadas en cambios ergonómicos con la intención de mejorar la geometría del mango de pistola convencional, ya que se considera ergonómicamente deficiente. El problema con este enfoque, es que las deficiencias no se encuentran únicamente en el mango, sino en la utilización de un punto de entrada fijo que fuerza a los cirujanos a mantener posiciones desfavorables. En este trabajo, se introduce el concepto "Libertad Postural" en el ámbito de la cirugía, este se basa en la hipótesis de que, si las herramientas no forzaran la posición de los cirujanos, estos mantendrían posiciones más favorables y cercanas al rango de posiciones neutras durante los procesos laparoscópicos. Los beneficios de este concepto han sido demostrados por medio de análisis de movimiento y de electromiografía de superficie, los cuales indican que la "Libertad Postural" es causante de un claro aumento de las posiciones neutras y de la reducción de la fatiga muscular, y han sido testeados por cirujanos en entornos simulados, los cuales encuentran beneficioso utilizar la "Libertad Postural" como característica base de este nuevo diseño de herramienta laparoscópica. En la sección final de este trabajo se propone un diseño que implementa el concepto de libertad postura con el cual se reduciría la fatiga muscular y los problemas musculo esqueléticos asociados a la práctica laparoscópica. Este diseño tiene la característica de actuar como una nueva sección del brazo, siendo una articulación que soporta los giros y grandes desplazamientos que normalmente tienen que desarrollar los brazos del cirujano. Además, esta solución es económica y fácil de fabricar, lo cual permitiría su uso por cirujanos de todo el mundo. / [CAT] La cirurgia laparoscòpia està considerada un dels principals avanços quirúrgics en les últimes dècades.

A més força al cirurgià a adoptar posicions no-neutres en falanges, mans, nines, i braços. Aquestes postures no-neutres són la principal causa de fatiga muscular i augmenten el risc de problemes musculo-esquelètics. Aquests problemes han sigut àmpliament estudiats per diferents equips d'investigació, els quals estan tractant de millorar l'experiència del cirurgià en el quiròfan. L'enfocament utilitzat en aquest estudi és diferent de l'utilitzat anteriorment per la majoria d'aquests equips, els quals solen proposes solucions basades en canvis ergonòmics amb la intenció de millorar la geometria del mànec de pistola convencional, ja que es considera ergonòmicament deficient. El problema amb aquest enfocament, és que les deficiències no es troben únicament en el mànec, sinó en la utilització d'un punt d'entrada fix que força als cirurgians a mantindre posicions desfavorables. En aquest treball, s'introdueix el concepte "Llibertat Postural" en l'àmbit de la cirurgia, aquest es basa en la hipòtesi que, si les eines no forçaren la posició dels cirurgians, aquests mantindrien posicions més favorables i pròximes al rang de posicions neutres durant els processos laparoscòpics. Els beneficis d'aquest concepte han sigut demostrats per mitjà d'anàlisi de moviment i de electromiografía de superfície, els quals indiquen que la "Llibertat Postural" és causant d'un clar augment de les posicions neutres i de la reducció de la fatiga muscular, i han sigut testats per cirurgians en entorns simulats, els quals troben beneficiós utilitzar la "Llibertat Postural" com a característica base d'aquest nou disseny d'eina laparoscòpica. En la secció final d'aquest treball es proposa un disseny que implementa el concepte de llibertat postura amb el qual es reduiria la fatiga muscular i els problemes *musculo esquelètics associats a la pràctica laparoscòpica. Aquest disseny té la característica d'actuar com una nova secció del braç, sent una articulació que suporta els girs i grans desplaçaments que normalment han de desenvolupar els braços del cirurgià. A més, aquesta solució és econòmica i fàcil de fabricar, la qual cosa permetria el seu ús per cirurgians de tot el món. / [EN] Laparoscopic surgery is considered one of the main surgical advances in the last decades, this technique has demonstrated numerous advantages compared to open conventional surgery and it is widely used in abdominal procedures around the world. For the patient, laparoscopic surgery suppose less post-operative pain, shorter recovery time, lower risk of infection, and reduction of the trauma among other benefits. For the surgeon, the situation is completely different, this practice requires more effort, concentration and mental stress than conventional open procedures. It forces the surgeon to adopt non-neutral postures with phalanges, hands, wrists, and arms being this non-neutral postures the main cause of muscular fatigue and high risk of musculoskeletal disorders. The poor ergonomic postures accelerate muscle fatigue and pain because, outside the neutral range, muscles require more energy to generate the same contractile force than in neutral position. This increase of muscular fatigue is associated with the potential to commit errors that may harm the patient during the surgery. Because this problem is widely studied and different research centers are already trying to improve their surgeons experience in the operation room, the approach used during this work is different than most of the ones presented in previous works. Generally, the solutions proposed are based on ergonomic changes in the handle shape of the instrument, because the conventional pistol-grip handle is considered ergonomically poor. But the problem is not only in the shape of the handle but also in the fixed point of entrance that force the positions for the surgeon despite the handle¿s shape. In this work, the concept of postural freedom in laparoscopic surgery is introduced and evaluated. The postural freedom concept is based on the hypothesis that the surgeon involuntarily would maintain neutral postures if the instrument does not force him or her to reach extreme position with the upper limbs. The benefits of this concept has been demonstrated, by means of electromyography and motion capture. It reduces the localized muscular fatigue and increases the number of neutral postures during laparoscopic simulations. In the final section it is proposed a design that implements the postural freedom concept with, according on the results, the potential to reduce the localized muscular fatigue and the musculoskeletal problems associated to the practice. The design proposed here acts as a new section on the arm, being an articulation that support the turns and big displacements that currently suffer the surgeon¿s body. The solution is affordable and easy to manufacture and could be used by surgeons worldwide. / Pace Bedetti, HM. (2019).

In der vorliegenden Arbeit wird die Synthese chromophorer Xerogele des Typs II auf Grundlage nucleophiler aromatischer Substitutionsreaktionen von Fluorarenen mit aminofunktionalisierten Trialkoxysilanen in Tetraethoxysilan als Lösungsmittel beschrieben. Die Herstellung von anorganisch-organischen Sol-Gel-Hybridmaterialien gelingt dabei in einer Eintopfreaktion. Neben kommerziell erhältlichen Fluoraromaten, wie z.B. 4-Fluornitrobenzen, wurden fluorfunktionalisierte Azomethine, Diazoverbindungen und Diphenylaminderivate eingesetzt. Die Synthese und Charakterisierung literaturunbekannter Fluoraromaten wird beschrieben. Besonderes Augenmerk lag auf der Reproduzierbarkeit der Xerogelsynthesen und der Charakterisierung der Xerogele durch Methoden der Festkörper-NMR- und UV/Vis-Spektroskopie sowie der Elektronenmikroskopie.

The ability to solve problems creatively has been crucial for the adaptation and survival of humans throughout history. In many real–life situations, cognitive processes are not isolated. Humans are social, they communicate and form groups to solve daily problems and make decisions. Therefore, the final output of cognitive processes can come from multi–brains in groups rather than an individual one. This multi–brain output can be largely different from the output that an individual person produces in isolation. As a result, it is essential to include team–level processes in cognitive models to make a more accurate description of real– world cognitive processes in general and problem solving in particular. This research aims to answer the general question of how working in a team affects creative problem solving. For doing that, first, we propose a computational model for multi-agent creative problem solving. Then, we show how the model can be used to study the factors that are involved in creativity in teams and potentially will suggest answers to questions such as, ‘how team size is related to creativity’.

Die Mechanochemie ist eine effekive und überzeugende Methode zur Herstellung von Alumniumhydroxidfluoriden (Al(OH)3-xFx) mit einem sehr geringen Fluorgehalt. Durch den Prozess des Mahlens werden strukturelle Defekte in den Kristalliten erzeugt, die zu einer zunehmenden Amorphisierung des Kristallsystems führen. Die partielle Fluorierung von Alumniumhydroxid während des Mahlprozesses führt dabei zu einer noch stärkeren Amorphisierung und zur Bildung von Alumniumhydroxyfluoriden. Eine wichtige Rolle bei der resultierenden Produktzusammensetzung spielt die Variation der Synthesebedingungen, wie der Grad der Fluorierung, der Dauer des Mahlprozesses und des Wassergehalt der Edukte. Folglich wurde zuerst der Einfluss von Wasser und dessen Bedeutung durch die verschiedenen Kombinationen von Oxid- und Hydroxid- (Al(OH)3, Al2O3), sowie Fluorid-Quellen mit oder ohne Kristallwasser (β-AlF3.3H2O, α-AlF3) bei der mechanochemischen Synthese von hochgestörten Alumniumhydroxidfluoriden untersucht. Um den optimalen Fluorierungsgrad zu ermitteln, wurden verschiedene Aluminiumhydroxidfluoride mit Al/F-Molverhältnissen von 1:1.5 bis 1:0.05 über die mechanochemische Syntheseroute hergestellt. Eine tiefergehende Charakterisierung der Struktur- und Oberflächeneigenschaften der entsprechenden Produkte erfolgte mittels XRD, 27Al- und 19F-Festkörper-NMR, thermischer Analyse, Stickstoffabsorptions- und Zeta Potentialmessungen. Mit γ-Al(OH)3 und β-AlF3•3H2O als Hydroxid- und Fluorid-Quellen wurden dabei ab einem Verhältnis Al:F von 1:0.25 und hin zu höheren Fluoridanteilen besonders ungeordnete Strukturen erzeugt. Der Fluorierungsgrad betrifft dabei besonders die Ausbildung von 4- und 5-fach koordinierten Al-Zentren, die sonst nicht in den Edukten vorkommen. Diese Spezies beeinflussen die Bildung von Alumniumoxid und ermöglichen den Phasenübergang zu α-Al2O3 schon bei tieferen Temperaturen. Der Einfluss der Mahldauer auf die Struktur und Oberfläche wurde am Beispiel von γ-Al2O3 im Detail untersucht. Die mechanochemische Synthese beeinflusst dabei die Absorption von Fluor an der Grenzschicht von γ-Al2O3 zu Wasser stark. Die Dauer des Mahlprozesses gewinnt daher einen großen Einfluss auf die entstehenden Produkte. Da Fluor nicht im Bulk von γ-Al2O3 vorkommt, kann mit der 19F-Festkörper-NMR eine Zuordnung der unterschiedlichen an der Oberfläche adsorbierten F-Spezies getroffen werden. / The mechanochemical approach opens a reliable and effective strategy for the formation of aluminium hydroxide fluorides with a very low F-content. Milling has the effect of introducing structural defects, causing amorphisation. The fluorination by milling creates a further and drastic increase of this degree of amorphisation. Synthesis conditions (milling time, fluorination degree, water content) play a crucial role in the product composition. Firstly, the significant role played by water in the mechanochemical synthesis of highly distorted aluminium hydroxide fluorides was evaluated. The importance of water in the synthesis was considered by a separated combination of O/OH sources (Al(OH)3, Al2O3) and fluorine sources with or without structural water (β-AlF3.3H2O, α-AlF3). Concerning the degree of fluorination, different aluminium hydroxide fluorides with varying Al/F molar ratios from 1:1.5 up to 1:0.05 were successfully synthesized by mechanochemical reactions. The characterization of the products by XRD, 27Al and 19F MAS NMR, thermal analysis, nitrogen adsorption and zeta potential techniques allows a detailed understanding of the structure and surface properties of the products. Using γ-Al(OH)3 and β-AlF3•3H2O as OH- and F-sources, respectively, strongly disordered products were obtained with an Al: F molar ratio higher than 1:0.25. The degree of fluorination affects the amount of 4- and 5-fold coordinated Al sites, not present in the reactants. Obviously, these species affect the phase transition to alumina, by decreasing the transition temperature of the formation of α-Al2O3. The influence of the milling time was considered by studying the power of a high energy ball milling process on the structure and at the surface of γ-Al2O3. The mechanochemical treatment strongly influences the adsorption of fluorine at the γ-Al2O3/ water interface. The time of the treatment has relevant importance on these processes. Since fluorine is not originally present in the bulk of γ-Al2O3, 19F MAS NMR studies allow the discrimination of different F-species adsorbed at the surface or present as metal fluoride particles in γ-Al2O3 powders after adsorption experiments.

À partir des enquêtes, le trafic n’est pas une donnée, mais il est plutôt construit à partir d’hypothèses portant sur les relations entre des origines et des destinations. En vue de reconstruire un trafic routier plus proche de la mesure, et sur un ensemble de tronçons routiers plus important, il apparait alors intéressant de partir de données de comptages issues de capteurs urbains. Notre postulat de départ part de ce constat. L’insertion de ces données d’observations du trafic routier fournit l’opportunité d’expérimenter les potentiels d’exploitations des capteurs pour estimer les niveaux de Pollution Atmosphérique Automobile (PAA) à l’échelle intraurbaine. Cependant, il est alors nécessaire de modifier la nature de la mesure en vue d’extraire une information sur la circulation routière, ce qui a été envisagé ici à travers la construction d’un modèle de simulation multi-agents. D’une manière plus générale, en partant de la donnée, c’est une démarche de construction de la connaissance sur les émissions de PAA qui est abordée tout au long de ce travail. La mise en œuvre de la démarche de modélisation SCAUP (Simulation multi-agents à partir de Capteurs Urbains pour la Pollution atmosphérique automobile) a été réalisée en trois temps : 1. En se focalisant sur les dispositifs de quantification du trafic routier à travers les capteurs urbains ; 2. En proposant une démarche de modélisation et de simulation de ces données pour le trafic routier ; 3. En se rattachant aux référentiels nationaux utilisés par les AASQA pour le calcul des émissions de PAA. L’ensemble se lie et s’intègre au sein d’une matrice technique qui constitue la colonne vertébrale de ce manuscrit à travers trois dispositifs interdépendants : la quantification, la modélisation et l’évaluation. Ce travail s’inscrit dans une démarche expérimentale de simulation du trafic routier pour le calcul des émissions de PAA. Parrainé par l’AASQA locale ATMOSF’AIR BOURGOGNE, il s’inscrit aussi dans une optique de recherche appliquée en appui de ces organismes en charge de la surveillance de la qualité de l’air. À l’heure où le big data entre dans de nouveaux questionnements quant aux capacités des chercheurs à en extraire une connaissance, nous proposons une démarche géographique en vue de replacer la donnée au centre d’une démarche de simulation originale du trafic routier (data-driven). / Based on surveys, traffic is constructed from assumptions about the relationship between origins and destinations. In order to rebuild a road traffic wich would be closer to observation and on a wider set of road sections, it appears interesting to use counting data from urban sensors : this is our starting point of view. The insertion of these in-situ dataset in the road traffic measurement provides the opportunity to experience the potential of sensors to estimate Traffic Air Pollution (TAP) levels at the intraurban scale. However, this requires to change the nature of these estimation, here through the construction of a model of multi-agents simulation, in order to extract more information on the road traffic. More generally, this work can be seen as a a knowledge building approach on TAP emisssions which is discussed throughout this work. The implementation of the SCAUP (multi-agent simulation from Urban sensors for traffic air pollution) approach was developped in three stages: 1. Focusing on the quantification of road traffic devices through urban sensors; 2. Proposing a modeling approach for road traffic data simulation ; 3. Using as a reference the national framework used by AASQA to calculate RTA emissions. All is integrated within a technical matrix that forms the spine of the manuscript through three interrelated systems: quantification, modeling and evaluation. This work is part of an experimental approach dedicated to the calculation of TAP emissions based on traffic simulations. Sponsored by the ATMOSF’AIR BOURGOGNE local AASQA, this work could also be used in an operational mode for these organizations in charge of the air quality monitoring. At a time when the big data enters into new questions about the ability of researchers to extract knowledge, we propose a geographical approach that enables to replace the data in the center of an original road traffic simulation approach (data- driven).
